IMPROVEMENT lN- CULTIVATO RS.

To all whom it may concern Be it known that I, W. D. JOHNSON, of Raleigh, in the county ofWake and State of North Carolina, have invented a new and useful Improvement in Cultivators; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being bad to the annexed drawings, making a part of this specification, in which- Figure 1 is a side view of my invention. Fig. 2 is a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in peculiar manner of constructing the frame of the implement, whereby, in combination with double shares, the same may be readily adapted for the cultivation of various crops and at the same time a very economical device obtained.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A A represent two wrought-metal bars, the back parts of which are curved upward to form handles, the shape of which is shown clearly in Fig. 1. The horizontal portions of the bars A A have an oblique position relatively with each other, and the front ends are encompassed by a square collar or loop, B, said collar or loop also encompassing the back end of the draft-bar G and the front end'of a bar, D, the back part of which is curved downward and penetrates the earth a certain distance, serving to prevent any casual lateral movement of the implement. (See Fig. 1.) The back end of the draft-bar U, as well as thefront ends of the bars D A A, are made of dovetail form, which, in connection with the collar or loop B, form a secure fastening or connection. The back parts of the horizontal portions of the bars A A are connected or braced by a rod or bar, D, the ends of which have screWthrea-ds cut on them and pass through the bars and have nuts on their outer ends. Bars D of greater or less strength may be used, in order to expand the oblique parts of the bars A more or less, as occasion may require. The draft-bar O is notched at its under side, as shown at a,

and a draft-hook, E, is fitted thereon, the lower part of the hook fitting into the notches and the upper part resting or hearing on the up per surface of the bar, as shown clearly in Fig. 1.

On the oblique parts of the bars A A cultivator-teeth of various shapes or patterns may be secured by means of loops b and keys 0. A cultivator tooth or share, d, may also be placed on the draft-bar G and secured to it in a similar way. Shares F for turning the earth may be attached to either bar A.

It will be seen from the above description that the implement may be readily adapted for cultivating various crops, as every variety of share or tooth may be applied to the bars A A, and the latter expanded or contracted, so as to render the device of greater or less width as the nature of the work may require. The frame also may be very quickly and cheaply constructed and still be very durable.

The curved bar D forms a simple, cheap, and eflicient means for preventing any lateral movement of the implement.

In case of transportation and storage the implement may be taken apart and packed within a small compass and the farts readily adjusted together for use when required.

I do not claim broadly a metallic frame, irrespective of the construction of the same, as herein shown, for metallic frames have been previously used and arranged in various ways; but

I do claim as new and desire to secure by Letters Patent-- The barsA A, curved so as to form handles at one end, and having horizontal oblique positions to form the body of the frame, the draftbar 0, and guide or retaining bar D, the front ends of the bars A A being connected or secured together by the collar or loop B, in com-' bination with the double scraper F, substantially as described, and for the purpose set forth.
